This role installs and manages a [gitea](https://gitea.io) server -
[Source code & screenshots](https://github.com/go-gitea/gitea).

Gitea is a Golang Git repository webapp, having the same look and feel as GitHub.

## Sample example of use in a playbook

The following code has been tested with Debian 8, it should work on Ubuntu as well.

```yaml
- name: "Install gitea"
  hosts: all
  vars:
    gitea_user: "gitea"
    gitea_home: "/var/lib/gitea"
    # To limit your users to 30 repos
    gitea_user_repo_limit: 30
    # Don't use a public CDN for frontend assets
    gitea_offline_mode: true

    # Some 'rendering' options for your URLs
    gitea_http_domain: git.yourdomain.fr
    gitea_root_url: https://git.yourdomain.fr

    # Here we assume we are behind a reverse proxy that will
    # handle https for us, so we bind on localhost:3000 using HTTP
    gitea_protocol: http
    gitea_http_listen: 127.0.0.1
    gitea_http_port: 3000

    # SSH server configuration
    gitea_ssh_listen: 0.0.0.0
    gitea_ssh_port: 2222
    # For URLs rendering again
    gitea_ssh_domain: git.yourdomain.fr
    gitea_start_ssh: true

    gitea_secret_key: 3sp00ky5me
    gitea_disable_gravatar: true
    # To make at least your first user register
    gitea_disable_registration: false
    gitea_require_signin: true
    gitea_enable_captcha: true

    gitea_show_user_email: false
  roles:
    - gitea
```

## Contributing
Don't hesitate to create a pull request, and when in doubt you can reach me on
Twitter [@thomas_maurice](https://twitter.com/thomas_maurice).

I'm happy to fix any issue that's been opened, or even better, review your pull requests :)

## Testing
Testing uses [molecule](https://molecule.readthedocs.io/en/stable-1.22/usage.html). To start the
tests, install the dependencies first. I would recommend you use [a virtual env](https://virtualenv.pypa.io/en/latest/) for that but who am I to tell you what to do.

```
pip install pew # install pew to manage the venvs
pew new ansible # create the venv
pip install -r requirements-travis.txt # install the requirements
molecule test # Run the actual tests
```

Note: you need Docker installed

### Known testing limitations
Currently it's mainly validating that the playbook runs, the lint is ok, and that kind of things.
Since it runs in Docker, we currently have no way to check if the service is actually launched by systemd
and so on. This has to be worked on.
